Benq W1070 is a screen really needed?!
I was going to paint my wall with the mix Sherwin Williams 6260 UNIQUE GRAY which i read on AVS to be a great option instead of a screen but then i ask my friend who does professional rear projection for movies and he said that its so bright that the screen or pain may not be necessary because its so bright and the Lux is 600 for the BenQ and the cinema projectors are at 100.
What do you guys think? I would worry if its just the wall the blacks wouldn't be as good. I also don't know how to do a bespoke calibration.?
